Crystal structure of (E)-1-(2-nitro-benzyl-idene)-2,2-di-phenyl-hydrazine. | LitMetric

Crystal structure of (E)-1-(2-nitro-benzyl-idene)-2,2-di-phenyl-hydrazine.

Acta Crystallogr Sect E Struct Rep Online

Facultad de Ciencias Químicas, Benemérita Universidad Autónoma de Puebla 72570, Puebla, Pue., Mexico.

Published: September 2014

The title compound, C19H15N3O2, shows an E conformation of the imine bond. The dihedral angle between the planes of the phenyl rings in the di-phenyl-hydrazine groups is 88.52 (4)°. The 2-nitro-benzene ring shows a torsion angle of 10.17 (8)° with the C=N-N plane. A short intra-molecular C-H⋯O contact occurs. In the crystal, only van der Waals contacts occur between the mol-ecules.
